This Part of BS 5992 specifies the basic dimensional modules to be used in determining the external dimensions of general purpose all-or-nothing relays and the location of their terminal and fixing centres. It applies equally to all such relays regardless of their type of construction (e.g. electromechanical, electronic, reed, etc.) and includes the height of the socket when the relay is socket-mounted.

It also defines the external dimensions and gives preferred values for these in terms of multiples of the specified modules.

This standard does not apply to relays standardized by the International Organization for Standardization (ISO) (TC 20, Aircraft and space vehicles) or to the internal construction of relays or to the size of fixing arrangements and terminals (see flow-chart).

The object of this standard is to state the following for the external dimensions and location of terminal and fixing centres for general purpose all-or-nothing relays:

  1. definitions (clause 2);
  2. basic module and recommended multipliers (clause 3) for:
    1. socket-mounted relays (clause 4);
    2. relays for printed circuit boards (clause 5);
    3. other relays (clause 6).

All dimensions given in this standard are in millimetres.

External dimensions are given in integer multiples of the basic module whose value is specified for the various types of relay.

NOTE The titles of the publications referred to in this standard are listed on the inside back cover.
